To @ZZ whom t may concern,.-

Be it known that I, CHARLES A. Rions, a citizen of the United States,Vresiding at Glenville, in the county of Cuyahoga and State of Ohio,have invented a certain new and useful Improvement in Bath-Tubs, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings. p

The object of this invention is to provide a bath-tub adapted for usewhere but limited space is available. My tub may be very satisfactorilyemployed on sleeping-cars, private cars, steamships, and in variousplaces where there is not room for an ordinary tub.

The tub consists, essentially, of a lower receptacle having secured toit in a water-tight manner a flexible tubular sheath adapted to be drawnupward and, in effect, continue the bath-tub to the desired height, thetub` being thusin operation a vertical bath-tub instead of la horizontalone. The invention comprehends such tub broadly.

The tub in an approved form is hereinafter more fully explained and itscharacteristics pointed out in the claims.

In the drawings, Figure 1 is a vertical centra] section through the tubwith the tubular extension in its elevated form, showing the tub readyfor use. Fig. 2 is a similar section with the vertical extension foldeddown into the tub. Fig. 3 is a horizontal section across the tub at thejoint of the flexible extension therewith. Fig. liis a detail in sectionshowing a portion of the clamping-ring and its eX- pander.

Referring to the parts by letters, A represents a round vessel whichforms the lower portion of the tub and may be made of metal, porcelain,or any other suitable substance and is provided with a suitable exit forthe water, as indicated at a. y

B represents the flexible extension of the tub. This is alarge tubemade, preferably, of rubber and secured at its lower end in awater-tight manner to the vessel A. This securement I prefer toaccomplish by an expanding ring C, which lies between apair of beads t',formed on the inner side of the tube B near its lower edge, the ringbeing expanded by suitable means to force the rubber tube intowatertight contact with the upper portion atV of the vessel A, which ispreferably cylindrical at its point. The expanding of the ring C may bevery conveniently accomplished by a right and left hand screw c,threaded into the two ends of the ring C and having a thumb-nut c' forturning it. This screw allows the ring to be expanded by hand, so thatthe rubber may be forced into water-tight contact ywith the vessel. Italso allows the easy unclamp- -ing of the ring and the removal of therubber extension for the purpose of cleaning. The upper edge of therubber extension'is provided with a series of hooks b2, which when therubber tube is folded up will preferably be within the vessel A andwhich are adapted when the tube is extended to hold it in such employedin connection with shower-baths,

but none to my knowledge where the sheeting was a closed tube secured toa tub in a water-tight manner. With my invention a .tub one foot and ahalf in diameter may very conveniently accommodate a large-sized person.Any seeming inconvenience from the vertical posture required is morefancied than real and is compensated for by the possibility of havingwater at any'height desired. The tub is convenient, as one simply stepsinto it and raises the tubular extension, hooking' it into place. Thegreatest feature of desirability about it, however, comes from the smallhoor-space required.

I claim- 1. In a bath-tub, a vessel, a flexible tubular upper extensiontherefor, and a clamping means for forcing the flexible extension intocontact with the vessel, substantially as described.

2. In a bath-tub, in combination, a vessel, a flexible tube extendinginside the vessel near its upper end, a ring within the tube,

and means for expanding the ring. to force the tube into intimateContact with the Vessel, substantially as described.

3. In a bath-tub, in combination, a vessel, a iexible water-tight tube,means for clamping the lower end of the tube in a water-tight manner tothe upper end of the Vessel, and means engaging the upper end of thetube for holding it in vertical position, substantially as described.

4. In a bath-tub, in combination, a Vessel, a flexible rubber tube, saidtube having an annular bead near its lower edge, a clampingring adjacentto said bead, and means for constraining said ring toward the vessel toforce the rubber tube into intimate contact with the vessel,substantially as described.

5. In a bath-tub, in combination, a Vessel,

a exible rubber tube extending into the same, said tube having a pair ofannular beads near its lower edge, a clamping-ring between said
